US lawmakers have already introduced hundreds of AI bills in 2025

Just over two months into 2025, the number of pending AI bills in the U.S. has grown to 781, according to an online tracking tool.

The tool, maintained by consulting firm MultiState, shows that the number of pending U.S. bills pertaining to AI now exceeds the total number of AI bills proposed in all of 2024 (743). In 2023, state and federal lawmakers proposed fewer than 200 AI-related bills.

A few recently proposed laws include Maryland’s H.B. 1331, a bill regulating the development and use of high-risk AI in consequential decisions; Texas’ expansive Texas Responsible AI Governance Act; and Massachusetts’ HD 3750, which would require healthcare insurance providers to disclose the use of AI for reviewing insurance claims.

just 66 days into 2025 and the number of artificial intelligence bills pending in the US now officially exceeds the total for ALL of 2024. 👀

The legislative chaos can largely be attributed to inaction at the federal level. So far, Congress has struggled to pass a comprehensive AI framework comparable to bills like the EU’s AI Act.

The Trump administration hasn’t shown an appetite for aggressive AI governance. In late January, Trump signed an executive order directing federal agencies to promote the development of AI “free from ideological bias” that promotes “human flourishing, economic competitiveness, and national security.” But Trump has yet to endorse major congressional AI legislation.
